One thought occurs to me: could the gasoline smell be coming from the 

engine compartment? If the 701 has the slots in the firewall for the rudder 

pedal steering rods like the 601XL, there is a ready passage way for all 

kinds of engine odors, including gasoline. The smell could be coming from 

other openings in the firewall as well. Just a thought.

the area dry with no sign of a leak, there is no fuel smell at all in the 

wings. The cabin smelled of gasoline when I opened the door as it always 

does. Just to be sure I've topped off both tanks and left the inspection 

covers off and will check it in the morning.

I also "have sniffed the rubber fuel line and can not detect an odor from 

it (well it does smell like rubber)."

Beats me-- I'm about to give up on it unless someone else has an idea.



I did install the new rubber landing gear blocks that ZAC now sells to 

replace the rubber hose. Big difference and very tuff material.

Is part of flying and our love for airplanes...  We have to admit that  Airplanes have a very pretty smell of gasoline and live with it.

 I prefer to get home from flying, Saturday evening with this wonderfull gasoline aroma inpregnated, than the most exquisite french parfume

I too have noticed the gasoline smell on several occasions.  Here is my 

hypothesis for what  may be happening with the 701.  I have the vented 

caps  and  it may be  when the tanks  are full or close to full, fuel 

can  slosh up to the lid and  a little escapes from the cap and runs 

down into the wing where the smell can linger for days.  I have sniffed 

the rubber fuel line and can not detect an odor from it (well it does 

smell like rubber).

 I have experienced the described "smell" as well since first

flight. I have inspected the fuel system several times for any leak and found
	


nothing. I recently ordered new fuel line that is claimed to not out gas through

the side wall, at $5 a foot from AS. I will let you all know if this solves my

fume issue.

A little additional insight to the gas "smell". Per the Zenith materials list the 701 uses about 18 feet of fuel line. I just measured the circumference (C) of the new AS line at 1 5/8 inch. If you multiply this C by the 18 feet of line and assume about 80% of this computed area is in the cabin and fuse area, you end up with about 2 sq. feet of surface area that potentially can out-gas fumes.  We all know that even a small amount of fuel can create a noticeable smell, it is possible the line I used is permeable to some of the VOC's in the fuel and might cause the "smell". The line that I just purchased is made by Parker and designed to prevent the out-gas problem. So if that is the source, then by replacement of the line with something designed for that problem, it should go away. If the line is not the problem, then I just spent $100 to eliminate the line as a source.

I'm now inclined to believe that Johann G is right-on, I have two of the  AS brass "homebuilder shut-off valves" and although there is no  noticeable leaking the smell does seem to be stronger in that area, and I have  checked every other possibility. I've discounted the permeable fuel hose idea,  because there is absolutely no fuel smell in the wings (after removing an  inspection plate). I can live with it --- just want to know the  cause.
